FEED-REGULATOR FOR GAS-GENERATORS.

Specication of Letters Patent.

Original application filed. J une 30, 1917, Serial No. 177,920.' Divided and this application led June 4, 1918,.

, Serial No. 238,236.

To all 'whom #may concer/n: ,c Be it known that I, CLARENCE D. BAIRD, a citizen of the United States, residing at Alexandria, yin the county,y of Dekalb and discharged and from `which it is conductedr to theburners and the object ofthe present invention is to. provide; means actuated through the lowering movement of the gas bell for automatically opening. the valve which controls the discharge of carbid .from the carbid hopper'into the generating cham- -berso that the apparatus will be entirely automatic in itsl operation.

Another object of the invention is to provide means whereby the distance to which the valve is. opened may be regulated so as to thereby regulate the quantity of carbid discharged at any one time and which means will be located eXteriorly'of they generator so as to permit'of ready accomplishment of .the desired adjustment without interrupting thefoperation of the generator.

In the accompanying drawings: Figure 1 is a perspective view of agas generator 'embodying the present invention; Fig. 2 is'a vertical lsectional view through the generator, the elements of the regulating device being shown'in elevation as also the carbid hopper; y

Fig. 3 is a view similar to Fig. 2 but illustrating a slight modification of the invention and showing also the hopper and valveJ in vertical section. Y a lIn the drawings the generatlng chamber Ais indicated by the numeral 1 and the Lcollecting and storage device isarranged beside the said generating chamber 1 and includes a tank indicated by the numeral 2, which in that form ofthe invention shown in Figs. 1

and l2 of the drawings is spaced fromthe generating chamber' 1, but in the form shown in Fig. 3k is either an integral partthereof or placed limmediately beside thel said generating chamber. The gas bell is indicated by the'numeral 3 andthe lower open end of this bell is, as is usual, immersed in water in the tank 2, the tank being open at its upper end. Gas generated within the chamber 1 is conducted through one or more pipes i from the said chamber to a collecting chamber indicated by the numeral 5. and located at the bottom of the tank 2, as shown inFigY 2 ofthe drawings, or this pipe may lead into the upperend of an annular gas collectingchamber as shown in Fig. 1. .Such a collecting-chamber isl shownin Fig. 3 of thedrawings and is indicated by the ynu-V meral 5, Vand whether oney form` or another Patented sept. 3,'1918.

TED STATES PATENT OFFICE" f i of collecting chamber be employed,` a'conf ducting pipe k6 leads fromA/the collecting chamber up into the bell 3 so as to discharge the generated gas into the saidk bell. An outlet pipe 7 leads, of course, from the bell to the supply main from which the gas is finally conducted to the burners. Of course, if the gas is not being consumed, the bell 3 will be elevated as the. generated gas collects therein 'and on the other hand asithe gas is consumed and the volume withinl the Y gas bell decreases, the bell will, of course, lowen The numeral 8 indicates the carbid hopper and 9 the valve which controls the supply of carbid from the hopper into the generating chamber 1. The valve 9 is provided with a stemrl() which fits slidably through a tubular guide 11 located centrally within the. hopper 8, and the upper end of this stem projectsv eXteriorly of the said Vhopper- The device embodying the present invention is designed to providefor downward movement of the valve 9 to permit carbid to flow into the generating` chamber when the gas bell 3 has lowered to aA predetermined point.V The device includesy a supporting t arm which is indicated by the numeral 12 and which extends laterally from the top of `the carbid hopper, andwhich arm supports .the pulley 13, the cable is led downwardly through an opening 17 formed in the said supporting arm 12 and is connected at its other end to a counterweight 18 which balances or nearly balances the weight ofthe bell 3. The supporting arm 12, is held upon the top of the carbid hopper by means of the base 19 of an upstanding bracket 20 upon which issupported for oscillatory movement a rock arm 21. Pivotally connected to one end of this arm is a rod 22 which extends downwardly through the opening 17 and which is provided at its lower end with a horizontally disposed eye, indicated by the numeral 23, and through which the cable 15 passes. Adjustably arranged upon the ca-V ble 15 is an abutment 24 clamped in any suitable manner to the said cable and located below they eye 23. A weight25 is fixed upon the rod2-2 and counterbalances or substantially counterbalances the Yweight of the valve 9. The upper end of the valve stein 10 is provided with a transverse pin 26which at its ends works in slots 27 formed in the spaced portions of the arm 21, the said arm being preferably formed 'from a suitable length yof bar metal bent upon itself midway of itsends to provide the said spacedportions. v

From the foregoing description of they invention it'will be understood that as the gas is consumed and its generation in the chamber 1 slackens, the bell v3 will lower carrying with it the stretch of the cable 15 whichis connected with the bell. As a result the abutment-2llwill engage the eye 23 whereupon the rod 22 will be raised thus rocking the arm 21 and causing lowering of the valve stem 10 and opening of the valve 9 to admit a charge of carbid through the'generating chamber.- Of course, the abutment 24 may 'be adjusted upon the cable 15 so as to cause opening of the valve when the bell 3 has descended to any predetermined position.

In both forms of the invention the abutment is located yexteriorly of the generating chamber and may, therefore, be conveniently adjustedupon the cable and in thatform of the invention shown in Figs. 1 and 2Y of the drawings, the weight 18 is suspended between the generating chamber and the tank 2. In the form shown in Fig. 3, however, a tubular casing 28is arranged within the generating chamber and opens at its yupper end through the top of the said chamber, andthe weight andthe stretch of the cable which is connected to it are housed in thiscasing.
